I wanted to preserve the submissions for each of the four Friday Night Fights rounds, since I didn't realize the PollDaddy system would remove the images once voting was closed. So without further ado, here are all received submissions!
Caution: Lots of big image files follow, so if you're on a slow connection, beware. Images are in order of the weekly themes, going Super Hero - Sci-Fi - Fantasy - Open.
(These entries missed the deadline, but they're awesome so I am putting them in anyway):
(also too late to be included in FNF, also too cool to not include here):
Phew! You can see why I'm glad I didn't have to personally choose any winners, because they're all so good. Great job everyone, take a bow and thanks for sharing your creations with us!
